Digital identity wallet

Digital identity wallet

Zetes project @Brussels, Belgium (2022). For many years, transactional and online services have relied on end users using devices such as desktop computers and laptops. Therefore, solutions for remote identity proofing and digital signatures have been designed to the characteristics of such devices. However, these devices are more and more replaced by mobile devices such as tablets and smartphones, which raises new challenges.

For example, smart cards and tokens, which are typically connected to desktop computers and laptops using USB devices, cannot be easily connected to smartphones, or cannot at all. Furthermore, given developments in cloud computing, solutions have emerged in the last few years where the process of digital signature creation is done in a distributed way by different systems that may be controlled by different actors.

This is why recent standards have introduced the concept of mobile identity (e.g. driving licence in association with a mobile device) and electronic signature created using a remote signature creation device (i.e. electronic signature device is replaced by cloud-based services offered and managed by a trusted service provider), which can be both made available to the end user through a digital identity wallet as a smartphone app.

The related standards are:

  • ISO/IEC 18013-5:2021 - Personal identification, ISO-compliant driving licence, Part 5: Mobile driving licence (mDL) application;
  • ETSI TS 119 432 - Electronic Signatures and Infrastructures (ESI), Protocols for remote digital signature creation;
  • CSC standard - Architectures and protocols for remote signature applications.

In this project, my tasks are first related to the analysis of these standards so as to investigate how they could be implemented in practice and what is their impact on the project scope. Then, my tasks are related to the analysis of business needs (whether internal or from the customer), software implementation (e.g. software releases and documentation) and project management (e.g. project coordination with the customer).


Identity proofing

Identity proofing

Zetes project @Brussels, Belgium (2021). Identity proofing consists in verifying for a given level of assurance that a person, who is claiming an identity, is indeed the correct person. This identity proofing process can be performed manually by a human operator, either on site (through physical presence) or online (remotely through videoconference), but also automatically (e.g. fully automated online or in a controlled environment).

At the European level, the European Telecommunications Standards Institute (ETSI) is working on technical specification ETSI TS 119 46 to lay the foundations on a new identity proofing standard, whose aim is to be applicable in areas such as the issuance of electronic identity (eID) and Know Your Customer (KYC) processes, with several person types considered: natural person, legal person, and natural person representing a legal person.

One of the objectives of this specification is to provide controls against two main identity proofing threats:

  • Falsified evidence: A person claims an incorrect identity using forged evidence;
  • Identity theft: A person uses valid evidence associated with another person.

Therefore, implementing identity proofing requires a risk-based and outcome-based approach where requirements can be tuned up to a desired level of assurance (i.e. degree of certainty) of the result, depending on the context (e.g. purpose of the identity proofing, regulatory environment, acceptable risk regarding the result of the process).

In this project, my tasks are related to the analysis of technical specification ETSI TS 119 46 so as to investigate what parts of the identity proofing process are already developed and available at Zetes (and therefore could be reused), how the missing parts can be implemented in practice and what are the possible impacts of the implementation on the existing products and solutions.
